摘　　要：随着公交优先思想的逐渐被接受,作为实现公交优先的主要载体———公交专用道系统自然而然被提上议程。针对大中城市道路交通拥堵和公交运行缓慢等状况,应用微观交通仿真软件TransModeler建立路网车辆运行模型。以哈尔滨市第5路公交为实例,提出优化方案,应用TransModeler对其进行优化仿真,通过仿真结果对方案实施前后各路段的交通流运行状况进行评价,证明本文提出的方案具有一定的科学实效性。同时表明应用TransModeler软件可以快速、有效的实现各个优化方案的对比,节省繁琐数据输入的时间,仿真输出数据简单明了,对今后公交线网优化仿真有很大的帮助。With the thought of bus priority accepted gradually, bus lanes system, as the main carrier to realize bus priority, was on agenda naturally. Aiming at the traffic congestion of large and medium-sized city road, and buses slowly moving condition, road network operational model was set up based on microscopic traffic simulation software TransModeler. Taking NO. 5 bus in Harbin city as an example, optimization simulation solution by TransModeler is given. Through simulation results of the traffic flow program sec- tion before and after implementation, the scheme proves some scientific effectiveness. At the same time, the results show that the ap- plication of TransModeler software can compare each scheme quickly and effectively, which saves tedious data entry time, simplify the output data, and will provide great help for optimizing future transportation network.
